Knob-and-tube wiring in insulation
Now I am back to the issue of dense-packed cellulose in a house where knob and tube is in most of the exterior walls. I see lots of older homes installing cellulose and or fiberglass blown into the walls....just as an energy upgrade not as a whole house redo (gutted and re-wired etc.)
What are the electrical codes saying with regard to knob and tube exposure to insulation that is blown in... is this safe?
